GM2 hydraulics experts possess over 30 years of experience in both programming and use of USACE HEC-RAS 1-dimensional computer application software, USFHWA SRH-2D, 2-dimensional software for hydrologic and hydraulic analysis, and mathematical modeling as well.  We perform, for both inland and tidal environments: Hydrologic, Hydraulic, FEMA Floodway, and Scour analyses for bridge and stream channel designs.  Additionally, as part of any riverine or tidal construction project, we will obtain all necessary federal, state, and local permits and regulatory approvals; and will adhere, and help to ensure that others on the project adhere, to all applicable environmental requirements.  For highway and roadway construction projects, we also provide specialized hydrologic and hydraulic analyses for roadside drainage designs.
